BRICK-MACHINE.

Specification of Letters Patent.

Patented Dec. 13, 1910.

Application filed June 27, 1910. Serial No. 569,187.

To all whom it may concern:

Be it known that I, HERMAN IV. LAMP- MAN, a citizen of the UnitedStates, residing at Lagrange, in the county of Lagrange and State ofIndiana, have invented a new and useful Brick-Machine, of which thefollowing is a specification.

This invention relates to hand brick machines of the type forming thesubject matter of U. S. Letters Patent No. 847,613, dated March 19,1907, and issued on the application of F. WV. Steinhofi'.

The object of the present invention is to improve, simplify andstrengthen the construction of device set forth in said patent, as wellas to render it easier to manufacture and use; furthermore, to increaseits durability and to decrease the expense attending its manufacture.

WVith the foregoing and other objects in View which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of invention herein disclosed can be made within the scope ofthe claims without departing from the spirit of the invention.

In the accompanying drawings forming part of this specification, Figure1 is a longitudinal vertical section through a brick machine constructedin accordance with the present invention, the machine being shown inposition upon a work bench adapted for convenient use therewith. Fig. 2is a transverse vertical section through the brick machine. Fig. 3 is aside elevation, partly broken away and in section, showing the brickmachine after it has been inverted and the back plate forced down towardthe compartment mold box so as to discharge the molded articlestherefrom. Fig. 4 is a detail view of a slight modification in the core.Fig. 5 is a sectional View taken at a right angle to Fig. 1.

Like reference numerals indicate corresponding parts in the differentfigures of the drawings.

The brick machine of the present invention preferably, although notessentially, is used in connection with a work bench or supportconsisting of the end pieces or legs 1-1 and the top piece 2, said toppiece being formed in one edge thereof with a cut away portion or slot 3into which the brick machine of the present invention can be fittedduring the operation of supplying the material which is to be molded.

The brick machine proper consists of a compartment mold box which isformed preferably of sheet metal and includes the parallel side plates4-4. Mounted between the side plates l are the cross plates 5. Each ofthe cross plates 5 is formed at each of the ends thereof with aplurality of extensions or lugs (S6, each of said lugs being extendedthrough a short vertical slot 7 in the adjacent side plate and upset orotherwise secured therein. By providing the side plates 1 with aplurality of short slots 7 to receive the extensions (5, the strength ofthe mold machine is materially increased. The cross plates serve toseparate the mold box into a plurality of mold compartments 8, 9 and 10,three of such compartments being shown in the drawings, although it isto be understood that this number may be increased or decreased at will.Extending transversely across the lower ends of each of the moldcompartments 8, 9 and 10 are two cross rods 1111 said cross rods beingpreferably disposed adjacent the ends of the compartments in which theyare located. Normally resting upon each pair of cross rods 11 in each ofthe compartments 8, 9 and 10 is a core plate 12 which forms the bottomof the mold box as shown in Fig. 1 and is held in proper position by thecross rods 11. Each of the core plates 12 preferably is provided on itsupper surface with a plurality of knobs or projections 13 whichpreferably consist of bolt heads, and are adapted to contact with theinner walls of hollow core members 16 formed of cast metal or othersuitable material. Each core member 16 is held in position in the moldcompartment in which it is located by means such as the bolt 17 whichextends through the upper surface of the hollow core 16 and through thecore plate 12, said bolt 17 being provided on its lower end with a nut18 and on its upper end with an enlarged head 19 which rests upon theupper surface of the hollow core. The bolts 17 serve to hold the hollowcores securely in position in the mold box and the projections or knobs13 by engaging the inner walls of said cores, serve to prevent thehollow cores from rotating or being displaced upon the core plates 12.Extending downward from the lower surface of each of the core plates 12at a point thereon approximately beneath the lower edge of the hollowcore plate 16 is a pair of connecting plates 2020 each of saidconnecting plates having its upper end bent into the form of a flange 21lying on the lower surface of the core plate 12 and being bolted orotherwise secured thereto by means of the bolts 13. Each of theconnecting plates 20 is formed at its lower end with a laterallyextending flange 23, the flanges 23 of each pair of connecting plates 20being directed toward each other and being bolted or otherwise connectedas indicated at 24 with a back plate 25 which extends in parallelismwith the three core plates 12. The longitudinal or side edges of theback plate 25 preferably are formed with upstanding integral flanges 27which are slightly separated from the outer edges of the connectingplates 20 and the flanges thereof as shown in Fig. 2.

For the purpose of facilitating the handling and unloading of the brickmachine, the side plates l of the compartment mold box preferably areextended beyond the end cross plates 5-5 as indicated at 30. Mountedbetween the parallel extensions 30 are the cross rods 31 on which aremounted the sleeves 32 which serve as handles for use in manipulatingthe machine.

In operation, the machine preferably'is placed upon the work bench orstand in the position illustrated in Fig. 1 and the cement or othermaterial is poured into the mold compartments 8, 9 and 10 and istroweled off, tamped or otherwise treated. After the material has setsnfliciently, the brick machine is removed from the work bench by meansof handles 32 and is inverted as indi cated in Fig. 8, after which theback plate 25 is forced downward toward the compartment mold box withthe result that the core plates 12 eject the molded articles from the Vcompartment mold.

In the modified construction shown in Figs. 4 and 5, the core members 16are slightly thickened as indicated at 35 at the portions thereof whichare in engagement with the bolts 13'.

The device of the present invention is I strong, simple, durable andinexpensive in construction as well as thoroughly practical andeflicient in use.

Vhat is claimed as new is:

1. A brick machine including a compartment mold box made up of sideplates and cross plates, the ends of the side plates being extendedbeyond the end cross plates and having handles mounted therebetween,cross rods in each of the compartments of the mold box, core platesmounted on said cross rods and having knobs projecting upward therefrom,hollow cores in engagement with said knobs at opposite portions and heldagainst movement thereby, a bolt extending through each of said coresand through the core plate, a back plate, and connecting plates mountedbetween the core plates and said back plates.

2. A brick machine comprising a compartment mold box consisting of sideplates having slots therein, a plurality of cross plates each having aplurality of lugs on each end thereof extending through the slots of theside plates and riveted therein, the ends of the side plates beingextended beyond the end cross plates, handles mounted between theextended ends of the side plates, a plurality of cross rods extendingacross the lower ends of each compartment of the mold box, a core platemounted in each compartment and resting normally on the cross rods, eachcore plate having a plurality of headed bolts, a hollow core inengagement with said headed bolts and held against movement thereby, abolt securing each core to its core plate, a back plate havinglongitudinal flanges, and a pair of connecting plates mounted betweeneach core plate and the back plate, each connecting plate having anupper flange secured to the core plate by said headed bolts, and a lowerflange secured to the back plate between the longitudinal flangesthereof.

In testimony that I claim the foregoing as my own, I have hereto affixedmy signature in the presence of two witnesses.
